MAGAZINE SHAVING BRUSH.

Application filed July 28, 1925. Serial No. 46,562.

' My invention relates to shaving brushes, and. has for its objecttoprovide a new'and useful reservoir brush of this character, and havingsimple and efficient means for filling the reservoir (without detachingany of the assembled parts) with a plastic lather preparation used forshaving. Also a simple and efiicient means for forcing the lather.preparation to the center of the brush as needed. Other objects are toprovide a reservoir brush in which the several parts are easilyseparable and renewable, any one 'or more parts being replaced as theyare worn out, or broken; and to provide a transparent reservoir so theamount of lather preparation contained therein can be ascertained at alance.

y invention will be more readily understood from the followingspecification and drawings, of which:

Figure 1 is a longitudinal sectional view of the brush.

Figure 2 is a view showin the method of attaching an ordinary shavingcream tube for refilling thereservoir. p

the pistonwith pack- Figure 3 is aview of ing'ring in place.

Figure 4 is a view of the rubber packing ring before placing on piston.

Referrin to the accompanying drawings, numeral 1 designates a tubularbrush handle, which is preferably made of transparent material such ascelluloid, and forms the reservoir 2 for holding the shaving cream orother plastic lather preparation. The tube or cylinder 1 is threaded asat 3 to receive the bushing 4 which may be made of hard rubber, or anyother suitable material. A P

. washer 5 is interposed between cylinder 3 and bushingto make an airtight joint for the purpose that will be described later.

The brush head 6 is surrounded by the ferrule 7 and passing through saidbrush head is the metal tube 8 which is secured to a head 9. The tube 8and head 9 being glued to the brush'head 6. The brush head 6 andattached parts 7, 8 and 9 have a friction fit in bushing 4. Theouter endof the tube 8, which extends into the brush 10, is drawn to a point andthreaded as at 11, to receive the tube 12 as will be described later.

The cylinder 1 is threaded at-its other end as at 15 to receive the cap16, which is provided with the axially disposed bearing 17 for one endof a preferably left hand threaded shaft 18, which. shaft is extended asat 19 receive'the knurled head 20; the shaft 18 is also provided withthe thrust collar 21, wh ch bears against the cap 16. \Vithin thecyllnder 1 is a piston or follower 25, which is axially threaded toreceive the shaft 18, and having a peripheral groove to receive therubber packing ring 26, which engages the walls of cylinder 1. As it isessential to have a tight fitting packing ring, I have designed thepiston to be easily and quicklyfitted with a new packing ring when sameis needed. The rubber packing ring 26 is cut smaller in diameter thanthe groove in the piston 25 and consequently when the packing ring isstretched when placed inthe groove a tight fit is assured between the vIn use the plastic lather preparation. is placed w1th1n the handleportion, or reservoir, 2 by placing'the tip of the collapsible tube 12,which ordinarily contains the lather preparation over the threaded end11 of the tube 8, and turning thetube 12 with a slight pressure forward.

The threads 11 will tap the soft metal of the tube 12 and thread thetube 8 into the tip making a tight fit between the tubes 12 and 8. v

The iston 25 which should be at its extreme orward position as at 30 inFig. 2, is then moved toward the upper end of the cylinder 1 by turningthe knurled head 20 in the left hand direction.

artial vacuum within the bushing 2 and tube 8 and the shaving cream willthen flow through thetube 8 into the bushing 4 and reservoir 2 as thepiston travels upward. The washer 5 insures an air tight fit between thecylinder 1 and bushing 4. The cap 16 is provided with a vent 28 to allowthe egress and ingress of air as the piston travels one tachthe tube 12.When it is desired to pro-.

duce a lather with the brush the knurled head 20 is turned slightly 'tothe right, which causes the piston 25 to travel downward and Thiscreates a force shaving cream through the tube 8 into the brush; thebrush is then Wetted and lather provided in the usual Way.

It is obvious from this that by virtue of the detachable parts asdescribed, any part may be replaced if Worn out or broken, and thisbrush and parts may be sold with that oint in view. V

lVhile I have described and shown my invention in its preferred form, Idesire to have it understood that such changes may be made in form,arrangement o1 parts, and

construction as will not depart from the,

spirit of my invention.
